What Are The Health Benefits Of Drinking Milk Before Bed? 

Now, to figure out the answer to the question, “Is drinking milk at night good or bad?”, first you need to understand what’s the overall health benefits of drinking milk. So, here are the main benefits of drinking milk before bed and in general (14):

May Help You Fall Asleep

One of the main reasons why people drink milk before bed is because it may help you fall asleep easier and faster. As was mentioned earlier, this may happen due to its certain components. For example, tryptophan, which occurs in various protein-containing foods, is an amino acid, which plays a significant role in the production of serotonin (3). That neurotransmitter, in turn, improves your mood, induces relaxation, and acts as a precursor in the production of the sleep hormone melatonin. This hormone helps regulate your circadian rhythm and prepare your body for sleep. Studies show that taking melatonin and tryptophan supplements may boost your sleep and reduce symptoms of anxiety and depression that occur at bedtime, thus potentially aiding in sleep disorders (1).

Can Help You Keep Hunger Pangs At Bay

The factor that promotes a positive inclination in the answer to the question “Is drinking milk before bed good for weight loss?” is its protein contents. When you are on a strict diet, and oftentimes feel hungry when you go to bed, you may find it difficult to fall asleep. It is only natural, as those horrible hunger pangs keep you awake, and invite thoughts about the food that is left in the fridge into your head. And that is when a glass of milk may come to rescue. It is filled with protein, which prolongs the feeling of fullness and helps you keep those hunger pangs and food cravings at bay.

Adds To Bone Health

It is general knowledge that calcium promotes bone health. It is an essential nutrient for strong teeth, bones, muscle movement, and nerve signals. Experts recommend consuming enough of this nutrient, to prevent osteoporosis and bone fractures. And milk is a great source of calcium (5). You can often find fortified milk, which due to the addition of vitamin D, is even more beneficial for your bones. 

Although calcium is necessary for the healthy bones, there are disputes, whether milk is really the best source of that micronutrient.

May Improve Cardiovascular Health

Another essential nutrient found in milk is potassium. It can help the blood vessels dilate and reduce blood pressure. Moreover, by accompanying your potassium consumption with the reduction of sodium (salt) intake, you may lower the risk of heart disease and stroke. The recommended daily requirement for potassium is 3400 mg in men and 2600 mg in women. 

Although milk is a great source of heart-beneficial potassium, it also contains saturated fat and cholesterol, which are the opposite, and may increase the chance of cardiovascular disease. That is why it is recommended that you consume dairy in moderation.

May Protect Against Cancer

As you already know, milk contains calcium and vitamin D, but what you perhaps didn’t know is that these two nutrients not only improve your bone health but may also help protect against cancer.

Consumption of calcium has been linked to the reduced risk of colon cancer or rectum cancer, due to its ability to protect the gut lining. However, you should remember that everything is good in moderation, and too much calcium may lead to prostate cancer.

Vitamin D might take part in the process of cell growth regulation. It may lower the chance of colon cancer, and possibly prostate and breast cancer. However, as with calcium, some research shows that vitamin D levels were linked to an increased risk of pancreatic cancer.

May Help You Fight Depression

Proper levels of vitamin D support the production of serotonin, which is responsible for your mood, sleep, and appetite. Research shows that there is a link between vitamin D deficiency and clinical depression (13). So, by drinking enough milk, you may be able to add to the production of serotonin, thus fighting depression.

Downsides Of Drinking Milk Before Bed

Although there are numerous benefits of drinking milk before bed, it may be not the best option for you, as it may also have the following downsides:


“Lactose” – this word is a curse for people who are lactose intolerant, and according to data, around 30-50 million Americans are estimated to have this condition (8). For those people, consuming milk before going to bed may turn their night into a literal nightmare with diarrhea, gas, bloating, cramps, and many other unpleasant, to say the least, symptoms.

Weight Gain

It was mentioned before that drinking a glass of milk before sleep may prevent hunger pangs and thus reduce food cravings, but you should not forget that milk, unlike water or tea, is relatively rich in calories. If you follow a diet that limits your caloric intake, you may be disappointed to find out that a cup of milk adds 149 calories to your diet. And as your metabolism slightly slows down as you sleep, those calories are a bit more difficult to burn. So, if you aim at slimming down and don’t want to sacrifice anything from your current diet, you may want to reconsider your bedtime routines.

Liver Functioning

A warm glass of milk may be a great sleep remedy, but it does not have a great impact on your liver. At night your liver is busy detoxing your body by clearing off various junk, and milk might interfere with that process by giving it something else to process instead. So, if you want your liver to work properly, you may want to avoid drinking milk or consuming anything with calories before bed.

Is Drinking Milk Before Bed Good For Weight Loss: To Drink Or Not To Drink?

Now that you know all the benefits and risks of drinking milk before bed, it is time to answer the main question: Is drinking milk before bed good for weight loss, and should you do it? And the answer is, it completely depends on what your priorities are. If your main target right now is weight loss, and your diet doesn’t allow any dairy or you can’t consume milk because it will surpass your allowed daily caloric intake, then you should better drink a glass of water instead. The same goes for intermittent fasting. If you stick to the rules of intermittent fasting, and you want to drink milk before going to bed, which is not a part of your eating window, then it is recommended that you avoid it. 

However, if you follow a less strict diet, prioritize your rest, and have experienced that drinking milk before bed really helps you doze off faster, then you may want to resort to that method, despite those additional calories. Just remember that too much is never good for you, especially if you are trying to lose weight, so it is better to keep it rather occasional than regular. 

If you can’t fall asleep without a glass of milk, try meditation and relaxation techniques. They may help you clear your mind of annoying thoughts and bring you one step closer to sleep.

If you tend to let yourself off the hook, raise the white flag when things get tougher than you expected, send yourself on an unconscious binge-eating trip – BetterMe app is here to help you leave all of these sabotaging habits in the past!
